The conceptual process of the EN Neighborhood Policy is similar to the EU’s enlargement policy, while the latter’s structure and methods are drawn heavily from those of the former. Compared to the EU Common Foreign and Security Policy, the implementation of EU Neighborhood Policy carries characteristics such as differential，bilateral，and coordinated operations. In achieving the objectives of prosperity, stability and good governance，the ENP has been less effective than the EU enlargement policy, but it is still a necessary policy.
